Liver regeneration is a crucial process involved in cellular proliferation, differentiation, and tissue repair. Calcium signaling impact key pathways like hepatocyte growth factor-Met-tyrosine kinase (HGF-Met) transduction pathway, the epidermal growth factor receptor (EGFR) signaling and Ca-mediated nuclear SKHep1 cell proliferation pathway. Intracellular hepatocyte calcium stores are considered as base for the induction of ca-mediated regeneration process. Calcium signaling interplays with HGF, TGF-β, and NF-κB signaling, influence stem cell behavior and triggers MAPK cascade. The mitochondria calcium is impacting on liver rejuvenation by regulating apoptosis and cell division. In conclusion, it is stated that calcium-signaling holds promise for therapeutic liver interventions.

Background: Overdose of acetaminophen (APAP), a commonly used antipyretic analgesic, can lead to severe liver injury and failure. Current treatments are only effective in the early stages of APAP-induced acute liver injury (ALI). Therefore, a detailed examination of the mechanisms involved in liver repair following APAP-induced ALI could provide valuable insights for clinical interventions.

Powdered collagen is emerging as a promising topical hemostat owing to its adaptability to various wounds, active hemostatic abilities, and biosafety. The reproduction of a bionic structure similar to natural collagen is crucial for effective hemostasis and bioactivity. Additional factors relevant to clinical application include antimicrobial properties, minimal immune response, and straightforward preparation.

Aims: Liver fibrosis predisposes patients to liver failure and hepatocellular carcinoma. Various markers, which can be calculated easily from serum parameters, have been reported to predict liver fibrosis accurately. This study investigated the prognostic factors, including blood-based markers for liver fibrosis of patients with hepatocellular carcinoma following initial curative hepatectomy.

Cells die by necrosis due to excessive chemical or thermal stress, leading to plasma membrane rupture, release of intracellular components and severe inflammation. The clearance of necrotic cell debris is crucial for tissue recovery and injury resolution, however, the underlying mechanisms are still poorly understood, especially . This study examined the role of complement proteins in promoting clearance of necrotic cell debris by leukocytes and their influence on liver regeneration.

Background & Aims: Hepatocyte transplantation has shown promise for genetic diseases of the hepatocytes but to date has shown limited efficacy for non-genetic forms of severe liver injury. Limited cell engraftment and poor function of donor hepatocytes in recipient livers impacts the clinical utility of hepatocyte cell therapy. The mechanisms underpinning this are poorly understood.
